Nancy Schoeffler, 63, was killed in a hit-and-run on West Burnside on March 31. Police have asked for the public's help in solving the case.

Police working on the hit-and-run of a Southwest Portland woman said today that the vehicle that killed her was a Honda or an Acura.

Forensic specialists, analyzing evidence from the scene on West Burnside near Southwest Tichner Drive, have concluded that Nancy Schoeffler was hit by a 1996 to 2008 black Honda or Acura sedan. The vehicle has a damaged hood and front windshield.

Schoeffler, 63, was hit March 31 while she was crossing West Burnside. The vehicle was headed west, said Lt. Robert King, a spokesman for Portland police. Her body was found at 11:20 p.m. after police received a report of someone lying in the street. Her family said she was out enjoying the night, walking her usual loop near her home.

Police are looking for two women in their mid to late 20s who were seen arguing outside a black vehicle in the QFC parking lot at Southwest Barnes and Miller roads, about two miles from the crash site. The women were described as having blonde hair, being short and stocky and wearing baseball caps that might have had the Portland Timbers logo on them. There was a home game that night.
